【问题描述】:
我正在使用 Firebase 云功能在我的应用程序中显示通知,而我面临的唯一问题是当应用程序关闭或后台通知不显示弹出时。 应用程序中使用了抬头通知,我确实收到了通知,但通知没有像应用程序处于前台时那样弹出。我已将频道和通知的优先级设置为高,但它仍然不起作用。
我的服务等级:
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
Log.d("msg", "onMessageReceived: " + remoteMessage.getData().get("message"));
Intent intent = new Intent(this, WebViewActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);
String channelId = "Default";
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, channelId)
.setSmallIcon(R.drawable.app_logo)
.setContentTitle(remoteMessage.getNotification().getTitle())
.setContentText(remoteMessage.getNotification().getBody())
.setAutoCancel(true).setContentIntent(pendingIntent)
.setDefaults(DEFAULT_SOUND | DEFAULT_VIBRATE)
.setPriority(Notification.PRIORITY_MAX);
NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel(channelId, "Default channel", NotificationManager.IMPORTANCE_HIGH);
channel.setShowBadge(true);
channel.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC);
manager.createNotificationChannel(channel);
}
manager.notify(0, builder.build());
}
